my child is 16years old, healthy and active in sports. She recently started feeling faint with severe headaches . she is always tired. Docter noticed irregylarity with one of her heart valves. He prescribed pur-blocka. She has since developed flu and her symptoms seem worse. Especially after exercise. How does her diet affect her wellbeing? Can she have antibiotics and flu medicine with the pur-blocka? She mentioned that she feels out of breath after starting to take the pur-blocka. She has been taking it for 7 days and developed flu like symptoms for the last 5 days. Regards, Mrs H.E. Kotzee
